"A paper by Philipp Jovanovic and Samuel Neves published in late April analyzed the cryptography used in the Open Smart Grid Protocol (OSGP), a group of specifications published by a European telecoms standards body. The protocol is used in more than four million devices, and said to be one of the most widely used protocols for smart devices today."

"The results? Not great.The researchers found that the "weak cryptography" can easily be cracked through a series of relatively simple attacks. In one case, the researchers said they could "completely" defeat a device's cryptography."
